Multi-Color Deep Hole Long Head Marking Pen with 20mm Pen Tip for Metal Wood Glass

This special purpose marking pen is built for tasks where a standard pen tip cannot reach. The 20mm long pen tip allows you to mark accurately inside deep holes, narrow grooves, and recessed areas on a wide range of materials. It works on metal, wood, glass, and colloids, making it a practical choice for workshops, trade counters, and industrial settings. The ink is fast drying, so marks stay put without waiting, and it is xylene free for a more pleasant working environment. Available in black, red, blue, and green, this pen gives you colour choices for colour-coding or high-visibility marking.

Features and Construction

Every aspect of this marking pen is designed for functional, reliable marking in challenging spots. The long tip, specially formulated ink, and colour range all support its core purpose.

Material and Build

The pen uses a xylene-free ink formulation that dries quickly on non-porous surfaces. This reduces the chance of smudging when you move the marked item. The pen body is standard size for comfortable grip, while the 20mm tip extends reach without making the pen unbalanced. No further construction details are available from the source.

Size and Practical Fit

The long pen tip is the standout measurement at 20mm. This length is ideal for reaching deep into small-diameter holes or tight corners that a regular marker cannot access. The pen is not oversized, so it still fits in a standard pencil case or tool drawer.

Uses and Placement

This marking pen is suited to both professional and DIY environments where precision marking in confined spaces is needed.

Event or Professional Use

Works best for tradespeople marking measurements on metal or timber, for inspectors tagging glass panels, or for assembly workers marking colloid components. The fast-drying ink means production flow is not interrupted by waiting for marks to set.

Everyday Home Use

Handy for marking storage boxes in the garage, labelling tools, or writing on glass jars and plastic containers. The four colour choices allow you to colour-code items for quick identification.

Benefits and Buying Value

This pen offers practical advantages for anyone who needs to mark inside cavities or on varied materials without specialist equipment.

Reuse and Low Maintenance

The xylene-free ink is less likely to cause irritation during long marking sessions, and the fast-drying formula resists smearing. The pen cap protects the tip from drying out between uses, making it ready for repeated tasks.

Why Choose This Product

If you need a simple, effective way to mark in deep or awkward spots on metal, wood, glass, or colloids, this pen provides a direct solution. Its long tip, combined with four colour options and a safer ink formulation, makes it a dependable choice without unnecessary extras.
